Side sleeping is one of the most popular ways to drift off, but it can cause a number of issues if you don't have the right mattress and pillow. In this guide, we're going to share some practical advice on choosing the best mattress and pillow for side sleepers, as well as our top product picks, so you can get the support you need for this specific sleeping style.
Side sleepers generally prefer a 5 or 6 on the firmness scale, which equates to a medium comfort. When it comes to choosing the right mattress for you, this is one of the most important considerations. The firmness scale is measured from 1 to 10, with 1 being the softest and 10 being the firmest. You will find that most mattresses typically range from 3 (soft) to 8 (firm), and side sleepers like to be in the middle of that range.
However, as spinal alignment is key to healthy side sleeping, your body weight will determine which firmness level is right for you. The heavier you are, the firmer your mattress should be.
It is a common misconception that the firmer the mattress, the more supported you will be. Back sleepers, for example, benefit from a firm mattress because their body weight can be evenly distributed across the mattress. But it's a different story for side sleepers, as the pressure is focused on the hips and shoulders, a fairly small surface area. Another common myth is that side sleepers should sleep on a soft mattress to compensate for the added pressure, but this isn't true either, because a mattress that is too soft won't be able to support the spine.
To ensure you have a comfortable and fully supported night's sleep, you want the top two layers of your mattress to be at least 8cm thick. Most mattresses typically have between two and five separate layers which work together to provide comfort, support, and stability. The top layer or two acts as the comfort layer of your mattress and is where most of the comfort and support you feel comes from. Not only that, but these layers are also largely responsible for heat and motion transfer. On higher-end mattresses, the comfort layer can be divided into a dedicated comfort layer (or layers) and a support layer (or layers).
The thickness of the comfort section is important. If it’s too thin, it won't provide enough support or pressure relief. If your body is on the heavier side, you’ll quickly sink through the top layers and actually rest on the base layer, decreasing your comfort levels. Instead, you'll need a thicker mattress that can take the added weight without compromising comfort and support. The downside is that thicker mattresses tend to trap more heat, which can make you hot in the night, but this can be mitigated through the use of certain sleep technologies.
The bottom layers of your mattress play less of a role in comfort, but they work together to form a solid foundation and play an important role in compression support. This is particularly important for heavier sleepers, who will sink further into their mattress. The construction of the lower layers is also integral for the durability of the mattress, as it is what will take the weight of your body for years to come.
The other important aspect to consider when choosing a mattress or pillow is the materials it is made of. Memory foam, pocket springs, Octasprings, and latex are the most popular materials, and each brings its own advantages. You can also get hybrid mattresses which combine two or more of these materials in different ways to create unique sleep experiences. What material you choose is largely a matter of personal preference, but each has its own benefits, which you can find out more about in our mattress buying guide.
It's important to bear in mind that most mattresses will feel great when you try them out for a minute or two in a shop, but you often won’t feel the aches and pains from misalignment until you've slept on it for a couple of nights. Your core alone has over 30 individual muscles, and any excess pressure or tension can lead to pain over time. For this reason, it can often be better to buy a mattress that comes with a sleep guarantee for a certain number of nights. Find out more about our 60-Night Comfort Guarantee.

Five body zones with differing strengths and densities of Octasprings contour to your body, meaning you'll be perfectly supported from head to toe. With plenty of bounce and a thick top layer, this mattress is great for heavy sleepers and couples alike.
Pillow support is especially important for side sleepers, as your neck will need to be fully supported in order to maintain proper spinal alignment and avoid causing any undue strain on your back, shoulders, or head. Many side sleepers suffer from neck pain, but most of the time this can easily be fixed by reconfiguring your pillows and realigning your neck and spine.
In simple terms, your head is further away from the mattress when you sleep on your side. If the gap between your head and the mattress isn't filled, your head will be tilted down towards the mattress, causing the neck to bend and leading to strained muscles and tendons. Likewise, sleeping with too many pillows or ones that are too thick will push your neck up and cause a similar problem. The key is spinal alignment, and that is why purchasing a pillow or pillows that are the right size is important.
Sleep is something we spend a lot of our lives doing, and the last thing you want it to wake up in the morning with feelings of tiredness, or worse, headaches and chronic pain. To help you overcome this problem, we've selected best pillows for side sleepers.
